Katy Perry isn't the only one that can Roar, especially when she criticizes an ex's performance in the bedroom.

Former fling and world famous DJ Diplo made a comment after Katy told James Corden that Diplo earns 3rd place as a lover behind John Mayer and Orlando Bloom.

Diplo shot back, tweeting "I don't even remember having sex... I won the bronze medal in sex Olympics."

To be fair, Katy was hesitant to even divulge the information and insisted that all three of the discussed lovers performed well between the sheets.

We guess Diplo just wanted to drop some fire in response to his former flame.
